A flat Universe from high-resolution maps of the cosmic microwave background radiation

Nature, 2000
The blackbody radiation left over from the Big Bang has been transformed by the expansion of the Universe into the nearly isotropic 2.73 K cosmic microwave background.

The Cosmic Microwave Background

2016
The millimeter waveband, between about 0.3 mm and 1 cm (Figure 7.1), has given us wonderful insights into the nature and distribution of interstellar matter, via the carbon monoxide spectral lines (section 5.7) and emission from warm dust grains (section 6.7).

The Cosmic Microwave Background

2018
The measurement of the acoustic modes of the cosmic microwave background have been perhaps the most exciting new astrophysical territory explored in the 21st century. This cosmological area includes the study of some of the earliest moments of the Universe, such as the significant change in state of going from a gas of ionized particles to one of atoms

Cosmic Microwave Background Fluctuations

2006
Several experiments have recently detected very low contrast, sub-horizon scale structures in the Cosmic Microwave Background (CMB). In the current cosmological model, these structures result from acoustic oscillations of the primeval plasma at recombination ( $z \sim 1100$ ).

The cosmic microwave background radiation

Reviews of Modern Physics, 1979
Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe. This paper is about the discovery
